SunSDR2 DX HF Transceiver Setup and Demo

Expert Electronics SunSDR2 DX HF 100W, 6M 50W, VHF 8W Transceiver with Direct Digitization and Direct Signal Synthesis

The SunSDR2 DX transceiver based on the well-known SunSDR2 PRO transceiver with several hardware improvements. It is a 100W-HF; 50W-6M; 8W-2M transceiver, very compact, has active cooling and improved supply system, meaning it’s perfectly suited for DXpeditions. Also, we’ve added a separate connector for an external ATU, thus SunSDR2 DX has all the functionality you got used to in our radios and even more. Improved hardware along with the ExpertSDR2 software makes this high-performance SDR transceiver the perfect base station. The evident choice for a true contester!

An opportunity to use the transceiver as a signal generator via DAC OUT connector (SMA connector)
An opportunity to use external filters in the middle of the RF path, using ADC IN and RX OUT (SMA connector)
A small delay in CW mode (about 10 ms)
Input for external 10 MHz reference oscillator
An opportunity to use the transceiver in SO2V mode
Full duplex or half-duplex modes***
Antenna switch with 2 HF antenna connectors and separate VHF antenna connector (Mini UHF connectors)
Internal power-meter for HF and VHF bands and SWR-meter for HF band
Ethernet LAN interface provides a fast and reliable connection to PC

* ** *** These functions are supported by the transceiver’s hardware, but is not implemented in the ExpertSDR2 software. They will be supported in the future ExpertSDR2 software releases.
